Expanders / extension modules
Presented expanders are integrated circuits or small modules that allow you to connect additional input/output lines to the microcontroller. This is a great solution when the original number of outputs in microcontroller is not enough to handle all the tasks necessary to complete the project. We have a wide range of various expanders, which are able to extend the number of outputs by different number of pins.

Lead-out expanders
In extension modules category we offer over a dozen different solutions. Our product range includes both small ICs in DIP packages for THT mounting (through-hole assembly) and more complex modules (with soldered ICs). In order to connect a device to a microcontroller, previously prepared sockets are used (for example for I2C interface), pins prepared for goldpin mounting or goldpins.
Solutions ready to use
Our product range includes, among other things, a wide selection of modules that are ready-made solutions. You can choose one of them and use in simple and fast way a pinout expander, expanding in this way possibilities of your microcontroller. We have devices designed specifically for use with Raspberry Pi, Arduino and Banana Pi, but will also work well with other microcontrollers. Among other things, we have expanders that increase the number of leads by 8 or 16 pins (analog or digital, often also bidirectional pins). They can expand the number of I2C, GPIO, PWM leads and many others. Mux Shield II is our proposed pin expander designed for Arduino, which is able to increase the number of leads by up to 48 pins (they can work bi-directionally as digital or as analog inputs).
We also offer small ICs in DIP type housings, designed for through-hole mounting (THT). These devices are the cheapest way to purchase your own expander and expand the capabilities of your microcontroller. If you are creating your own device where size or weight is important, this is a great solution for you. The modules we offer are ready-made projects that use similar devices but are adapted to different tasks. You can design your own board, which will be optimized for your device - just put your other necessary components on it and save space.
